Now that I've upgraded from Debian Etch to Debian Lenny, I can't seem to log into my Linksys router anymore. I already did some googling but I haven't really found anything useful. The thing is that I have perfect internet connectivity, that I can ping into the router, that I can ping the other machines on my home network - but I just can't bring up the configuration webpage for the router. When I type its address into firefox, I'm informed that "Iceweasel can't establish a connection to the server at 192.168.1.1". That seems pretty contradictory considering that I can do pretty much all the networking that I want. And as this worked perfectly fine on Etch, I'm seriously puzzled right now. Does anyone have a clue what could be wrong?

Note: I recently had the same issue with FreeBSD 6.2.

OK, problem solved by resetting. But why did this happen in the first place? I checked from one my other computers just before resetting and it failed as well.
